In addition to researching the national (domestic) law of Uruguay you will need to also research its obligations under international law.
Article 38 of the Statute of the International Court of Justice sets out the sources of international law:
The Court, whose function is to decide in accordance with international law such disputes as are submitted to it, shall apply:
a. international conventions, whether general or particular, establishing rules expressly recognized by the contesting states;
b. international custom, as evidence of a general practice accepted as law;
c. the general principles of law recognized by civilized nations;
d. subject to the provisions of Article 59, judicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law.
The most important source of international law are international conventions, also known as treaties or international agreements. This guide will provide information on finding treaties where Uruguay is a party. Please see the International Legal Research Guide for more detailed information on how to conduct international legal research, including how to find other sources of international law.
Treaty research requires finding a full-text copy of a treaty or international agreement, then checking the status to see if it has entered into force, whether a party has ratified it, or if there have been any amendments.
Copies of full-text treaties and status information can generally be found on the depositary's website. A depositary is a government or organization to which the treaty is entrusted. Responsibilities include accepting all notifications and documents relating to the treaty, examining whether formal requirements are met, and notifying the parties of relevant acts.
For assistance with understanding treaty terminology (e.g., signatory, reservation, accession) when looking at status information, please see the UN Treaty Glossary.
Uruguay is a member of the Organization of American States (OAS). The OAS, founded in 1948, consists of 35 member states.
The Organization was established in order to achieve among its member states—as stipulated in Article 1 of the Charter—"an order of peace and justice, to promote their solidarity, to strengthen their collaboration, and to defend their sovereignty, their territorial integrity, and their independence."
Today, the OAS brings together all 35 independent states of the Americas and constitutes the main political, judicial, and social governmental forum in the Hemisphere. In addition, it has granted permanent observer status to 70 states, as well as to the European Union (EU).
The Organization uses a four-pronged approach to effectively implement its essential purposes, based on its main pillars: democracy, human rights, security, and development.
